DETAILED DESCRIPTION

In some embodiments, such as shown in FIG. 1, a mattress foundation 10, which may be assembled from a kit, may include four frames 12, 14, including two side frames 12 and two end frames 14, interior support members 16, corner members 18 and deck panels 20, 22, including side deck panels 20 and intermediate deck panels 22 (a portion of the deck panels 20, 22 are cut away in FIG. 1 to show the interior support members 16). The side frames 12 and end frames 14 may be joined by the corner members 18 such that the side frames 12 and end frames 14, in the assembled state, form a generally rectangular frame structure. The interior support members 16 may extend between at least two of the four frames 12, 14. For example, the interior support members 16 may extend between the end frames 14 and may be coupled to the end frames 14. Upper support surfaces 24 of the end frames 14, side frames 12 and interior support members 16 may be located in substantially the same plane and may include apertures 26 therethrough for receiving fasteners therein, as discussed in further detail below. The deck panels 20, 22 may be positioned over the upper support surfaces 24 of the end frames 14, side frames 12 and interior support members 16, and apertures 28 and grooves 29 (FIGS. 7 and 8) in the deck panels 20, 22 may be aligned with apertures 26 in the end frames 14 and side frames 12. Fasteners assemblies 30 may be positioned through the apertures 26, 28 and may couple the deck panels 20, 22 with the end frames 14, side frames 12, and interior support members 16 to form a substantially planar deck surface 32.

As shown in FIG. 2, the side frames 12 may include a first elongated member 34, a second elongated member 36, and a connective structure, such as a plurality of struts 38. The first elongated member 34 may be oriented substantially parallel to the second elongated member 36 and the struts 38 may extend therebetween, and may couple the first elongated member 34 to the second elongated member 36 to form a substantially rigid side frame 12. The first elongated member 34 and the second elongated member 36 may each comprise a hollow elongated tube having a first end 40 that includes a first opening and an opposing second end 42 that includes a second opening. The tube may be a commercially available tube, such as a steel or aluminum tube, and may have a cross-sectional shape that is generally circular, rectangular, etc. As a non-limiting example, the tube may be a steel tube having a rectangular cross-sectional shape, such as a square cross-sectional shape. The tube may have cross-sectional dimensions (e.g., a width and a height) of about 0.75 inch (about 20 mm). The tube may have an average wall thickness of about 18 gage (about 1.2 mm). As another non-limiting example, the tube may be a steel tube having a cross-section generally shaped as a rectangle, and may have a first cross-sectional dimension (e.g., a width) of about 0.75 inch (about 20 mm), a second cross-sectional dimension (e.g., a height) of about 1.5 inches (about 40 mm), and an average wall thickness of about 18 gage (about 1.2 mm). Each strut 38 may also include a tube positioned with the ends thereof abutting the first elongated member 34 and the second elongated member 36, respectively. Each strut 38 may be coupled to the first elongated member 34 and second elongated member 36, such as by a weld, and the ends of each strut 38 may be sealed by the first and second elongated members 34, 36, respectively. In some embodiments, such as that shown in FIGS. 1 and 2, a longitudinal axis of each strut 38 of the side frame 12 may be substantially parallel with a longitudinal axis of each of the other struts 38 of the side frame 12. Additionally, a longitudinal axis of each strut 38 of the side frame 12 may be oriented substantially perpendicular to a longitudinal axis of each of the first and second elongated members 34, 36 of the side frame 12.

The first elongated member 34 and second elongated member 36 may each include discrete coupling features 44, such as apertures. For example, the first and second elongated members may each include discrete coupling features 44 formed near the first ends and the second ends thereof for coupling the elongated members 34, 36 with the corner members 18. The first elongated member 34 may also include discrete coupling features, such as apertures 26 (FIG. 1), formed in the upper support surface 24 and extending through the first elongated member 34 for coupling the deck panels 20 with the first elongated member 34. Additionally, the side frames 12 may include a protective coating thereon, such as one or more of galvanizing, clear coating, powder coating and paint.

As shown in FIG. 3, the end frames 14 may be configured similarly to the side frames 12, and may include a first elongated member 46, a second elongated member 48, and a connective structure, such as a plurality of struts 50. The first elongated member 46 may be oriented substantially parallel to the second elongated member 48, and the struts 50 may be positioned therebetween. The struts 50 may couple the first elongated member 46 to the second elongated member 48 to form a rigid end frame 14. The first elongated member 46 and the second elongated member 48 may each include a tube having a first end 52 having a first opening and an opposing second end 54 having a second opening. The tube may be a commercially available tube, such as a steel or aluminum tube having a cross-section generally shaped as one or more of a circle, a square, and a rectangle, as discussed above in relation to the elongated members 34, 36 of the side frames 12. As a non-limiting example, the tube may be a steel tube having a cross-section generally shaped as a square and having a cross-sectional dimension of about 0.75 inch (about 20 mm) and an average wall thickness of about 18 gage (about 1.2 mm). As another non-limiting example, the tube may be a steel tube having a cross-section generally shaped as a rectangle, and may have a first cross-sectional dimension of about 0.75 inch (about 20 mm), a second cross-sectional dimension of about 1.5 inches (about 40 mm), and a wall thickness of about 18 gage (about 1.2 mm). Each strut 50 may also include a tube positioned with the ends thereof abutting the first elongated member 46 and the second elongated member 48. Each strut 50 may be coupled to the first elongated member 46 and the second elongated member 48, such as by a weld, and the ends of each strut 50 may be sealed by the first and second elongated members 46, 48. In some embodiments, such as shown in FIGS. 1 and 3, a longitudinal axis of each strut 50 of the end frame 14 may be substantially parallel with a longitudinal axis of each of the other struts 50 of the end frame 14. Additionally, a longitudinal axis of each strut 50 of the end frame 14 may be oriented substantially perpendicular to a longitudinal axis of each of the first elongated member 46 and second elongated member 50 of the end frame 14. The first elongated member 46 and second elongated member 48 may each include discrete coupling features 56, such as apertures. For example, the first and second elongated members 46, 48 may each include discrete coupling features 56, such as apertures, formed near the first ends 52 and the second ends 54 for coupling the end frame 14 with the corner members 18. Additionally, the first elongated member 46 may include discrete coupling features, such as apertures 26 (FIG. 1), formed in the upper support surface 24 and extending through the first elongated member 46 for coupling the deck panels 20, 22 with the elongated member 46.

The end frames 14 may additionally include coupling features for coupling the end frames 14 to the interior support members 16. In some embodiments, as shown in FIGS. 1 and 3, the end frames 14 may include brackets 58 that may have a generally U-shaped cross-section. For example, about 0.25 inch (about 6 mm) lengths of metal U-shaped channel may be welded to the first elongated member 46 of the end frames 14. In additional embodiments, the end frames 14 may include other discrete coupling features, such as apertures, for coupling the end frames 14 to the interior support members 16 with fasteners, such as bolts (not shown). Additionally, the end frames 14 may include a protective coating thereon, such as one or more of galvanizing, clear coating, powder coating and paint.

As shown in FIG. 4, the interior support members 16 may include a tube having a first end 70 configured to couple with an end frame 14 and a second end 72 configured to couple with another end frame 14. The tube may be a commercially available tube, such as a steel or aluminum tube having a cross-section generally shaped as one or more of a circle, a square, a rectangle, etc. As a non-limiting example, the tube may be a steel tube having a cross-section generally shaped as a square and having a cross-sectional dimension of about 1.25 inch (about 20 mm) and an average wall thickness of about 18 gage (about 1.2 mm). As another non-limiting example, the tube may be a steel tube having a cross-section generally shaped as a rectangle, and may have a first cross-sectional dimension of about 0.75 inch (about 20 mm), a second cross-sectional dimension of about 1.5 inches (about 40 mm), and an average wall thickness of about 18 gage (about 1.2 mm). The interior support members 16 may additionally include a discrete coupling feature, such as one or more apertures 26 formed therethrough, for coupling the interior support members 16 to the deck panels 20, 22, such as with a fastener assembly 30 as discussed in further detail below. Additionally, the interior support members 16 may include a protective coating thereon, such as one or more of galvanizing, clear coating, powder coating and paint.

As shown in FIG. 5, the corner members 18 may include a tubular member having an arcuate segment 62 and at least one substantially straight end segment 64. The arcuate segment 62 may be shaped generally as a circular arc subtending a right angle (i.e., about 90 degrees). As a non-limiting example, the arcuate segment 62 may be defined by a circular arc having a radius of about 3 inches (about 75 mm). In some embodiments, the substantially straight end segments 64 may have an outer dimension that is smaller than an inner dimension of an opening of the ends 40, 42, 52, 54 of the elongated members 34, 36, 46, 48 of the end frames 14 and side frames 12. As a non-limiting example, the end segments 64 may have a length of about 3 inches (about 75 mm). In some embodiments, the corner members 18 may be formed from a tube having a cross-sectional shape and size that is substantially similar to the elongated members 34, 36, 46, 48 of the end frames 14 and side frames 12. The tube may be a commercially available tube, such as a steel or aluminum tube having a cross-section generally shaped as one or more of a circle, a square, a rectangle, etc. As a non-limiting example, the tube may be a steel tube having a cross-section generally shaped as a square and having a cross-sectional dimension of about 0.75 inch (about 20 mm) and an average wall thickness of about 18 gage (about 1.2 mm). As another non-limiting example, the tube may be a steel tube having a cross-section generally shaped as a rectangle, and may have a first cross-sectional dimension of about 0.75 inch (about 20 mm) a second cross-sectional dimension of about 1.5 inches (about 40 mm), and an average wall thickness of about 18 gage (about 1.2 mm). In some embodiments, the end segments 64 of the corner members 18 may include a portion having a reduced outer dimension to allow the end segments 64 to be inserted into the elongated members 34, 36, 46, 48 of the end frames 14 and side frames 12. For such embodiments, the ends of a tube may be swaged to reduce the outer dimension thereof or a tube having a smaller outer dimension may be inserted into the end of the tube and welded thereto to form the substantially straight end segments 64. Additionally, the central segment of the tube may be bent to form the arcuate segment 62 of the corner member 18.

In additional embodiments, the corner members 18 may be formed integrally with one or more of the side frames 12 and the end frames 14. For example, and as shown in FIG. 19, the corner members 18 may be integral with the side frames 12 and the corner members 18 may each have a single end segment 64 for coupling with the end frames 14.

In further embodiments, and as shown in FIG. 20, the corner members 18 may be joined, such as by one or more struts 96, to form four corner assemblies 98, each corner assembly including two corner members 18. In such embodiments, the side frames 12 and end frames 14 may include a reduced number of struts. In some embodiments, the side frames 12 and end frames 14 may each include a single strut. Additionally, as is shown in FIG. 19, the corner members and frames may be configured such that the elongated members 34, 36, 46, 48 of the end frames 14 and side frames 12 may be configured to slide within the end portions 64 of the corner members 18.

The end segments 64 may include apertures 66 (FIG. 10) formed therein. Spring buttons 68 may be positioned within and protrude through the apertures 66 for use in coupling the corner members 18 with the end frames 14 and side frames 12. Additionally, the corner members 18 may include a protective coating thereon, such as one or more of galvanizing, clear coating, powder coating and paint.

In some embodiments, the deck panels 20, 22 may be coupled to the upper support surfaces 24 of the end frames 14, side frames 12 and interior support members 16 with fastener assemblies 30, such as that shown in FIG. 6. The fastener assemblies 30 may each include a machine screw 76, a top flat washer 78, a bottom flat washer 80, a lock washer 82 and a nut 84. For a non-limiting example, the fastener assembly 30 may include a one-quarter (¼) inch combination truss head screw, a top one inch flat washer, a bottom three-quarter (¾) inch flat washer, a one-quarter (¼) inch lock washer, and a one-quarter (¼) inch wing nut. The machine screws 76 may be positioned through the apertures 26 in the end frames 14, side frames 12, interior support members 16 and within apertures 28 and grooves 29 of the deck panels 20, 22. The top flat washer 78 may be positioned on the shaft of the screw 76 and between the head of the screw 76 and a surface of the deck panels 20, 22. The bottom flat washer 80 may be positioned over the shaft of the screw 76 adjacent a surface of the end frames 14, side frames 12 or interior support members 16 that is opposite the upper support surface 24. The lock washer 82 may be positioned on the shaft of the screw 76 adjacent the bottom flat washer 80. Finally, the nut 84 may be positioned on the shaft of the screw 76 adjacent the lock washer 82.

As shown in FIG. 1, the deck panels 20, 22 may include two side deck panels 20 (FIG. 7) and one or more intermediate deck panels 22 (FIG. 8). The deck panels 20, 22 may comprise a sheet material such as one or more of plywood, corrugated plastic, and expanded sheet metal. As a non-limiting example, the sheet material may be a plywood sheet having an average thickness between about 7 mm and about 9 mm. As another non-limiting example, the sheet material may be a corrugated plastic sheet having an average thickness of about 10 mm. In some embodiments, the sheet material of the deck panels 20, 22 may have a shape and density such that one square meter weighs about 1.5 kg or less. The side deck panels 20, 22 may be sized and shaped to cover at least a portion of a side frame 12, at least a portion of the end frames 14 and at least a portion of an interior support member 16. The side deck panels 20 may include two corners 74 sized and configured to cover and substantially conform in shape to the corner members 18. As a non-limiting example, two corners 74 of the side deck panels 20 may be rounded to define a circular arc having a radius of about 3 inches (about 75 mm). The intermediate deck panels 22 may have a substantially rectangular shape and may each be sized and shaped to cover at least a portion of at least two intermediate support members 16 and at least a portion of the end frames 14. In some embodiments, the entire peripheral edge of each deck panel 20, 22 may be fully supported by the upper support surfaces 24 of one or more of the end frames 14, side frames 12 and interior support members 16. In additional embodiments, the entire peripheral edge of each deck panel 20, 22 may not be fully supported by the upper support surfaces 24. For example, in some embodiments, a deck panel 20, 22 may be oriented substantially perpendicular to the interior support members 16 and a section of the peripheral edge of the deck panel 20, 22 may span between more than one interior support member 16 such that the peripheral edge is unsupported between the interior support members 16.

Optionally, a cover 86 (shown schematically in FIG. 9) may be positioned over the assembled mattress foundation 10, and may be included in a mattress foundation kit that includes an assembled or unassembled mattress foundation 10. In some embodiments, the cover 86 may be a textile cover that may be positioned over the mattress foundation 10. The cover 86 may include an opening that may be at least partially closed upon positioning over the mattress foundation 10 to secure the cover to the mattress foundation 10, such as by one or more of a zipper, hook and loop fasteners (i.e., VELCRO® fasteners), buttons, snaps, elastic webbing, and other textile closures. In additional embodiments, the cover 86 may be provided with clips for securing the cover 86 to the second elongated members 36, 48 of the side frames 12 and end frames 14, respectively. In yet further embodiments, the cover 86 may be simply draped over the mattress foundation 10 (when assembled).

As shown in FIG. 9, the components of the mattress foundation 10, including the end frames 14, side frames 16, corner members 18, deck panels 20, 22, fastener assemblies 30 and optional cover 86, may be included in a kit 88 that may be packaged in a shipping box 90. The shipping box 90 may have a size, shape, and weight that enables the shipping box 90 to be shipped by standard shipping couriers, as discussed below.

In some embodiments, the shipping box 90 may have a generally rectangular shape (i.e., the shape of a rectangular prism), and may have a height, a length, and a width. The total sum of the length and the girth (the girth is the sum of the two widths and the two heights) may be about 130 inches or less in some embodiments of the invention. Referring to FIG. 9, as a non-limiting example, the shipping box 90 may be configured for shipping a queen-size mattress foundation 10, and may have a height D1 of about 4 inches, a width D2 of about 16.5 inches, and a length of about 79.4 inches (the length is not labeled in FIG. 9, as the length extends perpendicular to the plane of the cross-sectional view of FIG. 9), and a combined two times height D1, two times width D2, and length of about 120.4 inches. In embodiments in which the shipping box 90 is not a rectangular prism, the shipping box may have a combined length and lateral circumference (i.e., girth) of about 130 inches or less.

In some embodiments, as shown in FIG. 9, the deck panels 20, 22 may be stacked at one lateral side of the shipping box 90, and the side frames 12 may be positioned side by side adjacent the deck panels 20, 22. The end frames 14 may be positioned side by side adjacent the side frames 12 and the coupling features (i.e., the brackets 58) for coupling the end frames 14 to the interior support members 16 may be positioned away from the side frames 12. Relatively small components, such as the corner members 18 and fastener assemblies 30, may be positioned between the struts 38, 50 of the side frames 12 and end frames 14. The interior support members 16 and the cover 86 may be positioned side by side in the shipping box 90 adjacent the end frames 14. Additionally, packing materials (not shown), such as one or more of cardboard, paper, plastic and foam, may be positioned around and between the components of the kit 88 within the shipping box 90 to reduce movement of the components within the shipping box 90 and to prevent damage to the components.

In some embodiments, a kit 88 for a mattress foundation 10 as described herein may have a total weight of about 100 pounds or less. In additional embodiments, a kit 88 for a mattress foundation 10 as described herein may have a total weight of about 90 pounds or less. As a non-limiting example, a kit 88 that includes a mattress foundation 10 as illustrated in FIG. 1 and sized and configured for a queen-size mattress may weigh about 78 pounds when using steel tubing for the frames 12, 14, the corner members 18, and interior support members 16, and when using plywood for the deck panels 20, 22. A similar embodiment sized and configured for a king-sized mattress may weigh about 86 pounds. The weight may be even less if lower density materials are used, such as aluminum tubing for the frames 12, 14, the corner members 18, and interior support members 16, and corrugated plastic for the deck panels 20, 22.

In view of the relatively small size and weight of the mattress kits 88 described herein, the mattress kits 88 may be transported via courier services, such as UNITED PARCEL SERVICE® at their standard rates, which are substantially less expensive than their rates for oversize packages (for example, packages having more than 130 inches in length plus girth). The mattress kits 88 may also be transported with passenger vehicles, such as passenger cars, passenger vans and passenger sports-utility vehicles. Additionally, after using a mattress foundation 10, the mattress foundation 10 may be disassembled for removal and transportation to a new location where it may be assembled again. A disassembled mattress foundation 10 boxed as a kit 88 may also allow a relatively large number of mattress foundations 10 to be stored in a warehouse or retail storeroom when compared to the space requirement for conventional box springs using to support mattresses. Thus, embodiments of the present invention provide many advantages over conventional box springs used to support mattresses.

The mattress foundation 10 may be assembled at a point-of-use location, which may allow the mattress foundation 10 to be assembled in locations that may not be accessible with conventional box springs. If the mattress foundation kit 88 is contained within a shipping box 90, the kit 88 may be removed from the box 90. As shown in FIGS. 10 and 11, spring buttons 68 may be inserted into the ends of corner members 18 such that the button portions 92 of the spring buttons 68 extend through apertures 66 near the ends of the corner members 18, and the button portions 92 are biased into the apertures 66 by the spring portion 94. The ends of the corner members 18 then may be aligned with the openings in the ends 40, 42, 52, 54 of the elongated members 34, 36, 46, 48 of the side frames 12 and the end frames 14, respectively, as shown in FIGS. 11 and 14. Next, the button portions 92 of the spring buttons 68 may be pushed into the apertures 66 of the corner members 18 to facilitate insertion of the ends of the corner members 18 into the openings in the ends 40, 42, 52, 54 of the elongated members 34, 36, 46, 48 of the side frames 12 and the end frames 14, respectively, as shown in FIG. 12. Upon alignment of the button portions 92 of the spring buttons 68 with the coupling features 44, 56 of the frames 12, 14, the button portions 92 may be biased into the coupling features 44, 56 of the frames 12, 14 by the spring portion 94, as shown in FIGS. 13 and 15, which may secure the corner members 18 and frames 12, 14 together. Although spring buttons 68 are described for fastening the corner members 18 to the frames 12, 14, other fastener assemblies, such as screw and nut type fastener assemblies, may also be used.

After securing each of the corner members 18 with the side frames 12 and end frames 14, the interior support members 16 may be coupled to at least two opposing frames, such as to the opposing end frames 14. As shown in FIGS. 16 and 17, the ends 70, 72 of the interior support members 16 may be positioned at discrete coupling features of the end frames 14, and may be coupled to the end frames 14. For example, the ends 70, 72 of the interior support members 16 may be positioned within the U-shaped brackets 58 of the end frames 14. Upon coupling each of the interior support members 16 to the end frames 14, an upper support surface 24 of each of the end frames 14, side frames 12, and interior support members 16 may be positioned on substantially the same plane.

Next, the deck panels 20, 22 may be positioned on the upper support surfaces 24 of each of the end frames 14, side frames 12, and interior support members 16. As shown in FIG. 1, the edges of the deck panels 20, 22 may be positioned over the upper support surfaces 24 of each of the end frames 14, side frames 12, and interior support members 16. The apertures 28 in the deck panels 20, 22 may be aligned with apertures 26 in the side frames 12 and end frames 14, and grooves 29 at located at the seams between the deck panels 20, 22 may be aligned with apertures 26 of the interior support members 16. Screws 76 of the fastener assemblies 30 may then be positioned through the apertures 26, 28 and the fastener assemblies 30 may be utilized to couple the deck panels 20, 22 with the end frames 14, side frames 12, and interior support members 16 to form the deck surface 32. Upon installation, the deck panels 20, 22 may extend over the U-shaped brackets and secure the interior support members 16 within the U-shaped brackets 58 of the end frames 14.

Optionally, corner plates 100 may be positioned over the corner members 18 of the mattress foundation 10, such as shown in FIG. 20. The corner plates 100 may be placed over and substantially conform to the corner members 18 and cover an opening between the corner members 18 of the mattress foundation 10. The corner plates 100 may provide a curved surface at the corners of the mattress foundation 10 and may improve the appearance of the mattress foundation 10. For example, when a cover 86 is installed over the mattress foundation 10 the corner plates 100 may prevent the cover 86 from being dimpled or indented at the corners and may provide a relatively smooth corner surface. In some embodiments, the corner plates 100 may each be formed from sheet metal that may be bent to conform to the outer curvature of the corner members 18. Additionally, each corner plate 100 may include integral clips 102 that may hold the corner plate 10 over the corner members 18 of the mattress foundation 10. Optionally, the corner plates 10 may be fastened to the mattress foundation 10 by other fastening devices as will be recognized by persons having ordinary skill in the art.

Finally, the cover 86 may be positioned over the deck surface 32 and frames 12, 14 and optionally secured thereto. Upon assembly, the mattress foundation 10 may be positioned on a conventional bed frame (not shown) and utilized in a manner similar to a conventional box spring. Additionally, the mattress foundation 10 may be positioned directly on a floor (not shown) and a bed frame may not be utilized. In yet further embodiments, castor wheels or leg supports (not shown) may be attached directly to the mattress foundation 10 to support the mattress foundation above the surface of a floor without the use of a bed frame. In some embodiments, the mattress foundation may be completely assembled without the use of any tools.
